Bug Description

10.010 - Maverick Meerkat

alsa driver: 1.0.23

I want to hear sounds from the mobile speakers.

I only hear sounds from headphones, if plugged-in, but when I unplug the headphones nothing happens, and still no sound comes out from the speakers.

Can you reproduce this symptom using the latest daily build of the
sound drivers? Please see
https://wiki.ubuntu.com/Audio/InstallingLinuxAlsaDriverModules.

Solved

I found online the solution..

with the command:
gksudo gedit /etc/modprobe.d/alsa-base.conf
I opened the alsa-base.conf file, then added at the end the line:

options snd-hda-intel model=auto

it worked... thanks anyway!

Is there a subwoofer on this laptop?

Also, please try linux-alsa-driver-modules after removing the model=auto quirk. There is an automatic quirk for your laptop's manufacturer, and we need to verify that it works on your laptop. If you have a subwoofer in it, we also need to verify that the new driver does not break it.

The use of the latest daily build does not seem to solve the problem for me. The sound from the headphones does not work anymore, too.
The 7730g does have a subwoofer.

Oh, sry the headphones are working. I set the volume on the headphones itself to 0 ;)

Hi,

A lot of things has happened in the driver since this issue was reported. Acer Aspire 7730G is now using the auto model and has pin fixes to enable subwoofer. Is this still an issue on Ubuntu 12.04, and/or Ubuntu 12.04 with DKMS modules installed ( https://wiki.ubuntu.com/Audio/UpgradingAlsa/DKMS )?

summary:	- Audio doesn't work with notepad's speakers, but only with headphones + [Aspire 7730G] Audio doesn't work with notepad's speakers, but only with + headphones
